HUB STRUCTURE FOR WHEELS.

Specification of Letters Patent.

Patented A r. 1, rate.

Application filed August 13, 1917. Serial No. 185,998.

To all whom it may concern:

Be it known that 1, CHARLES SCHENCK, a

' citizen of the United States, residing at Philadelphia, in the county of Philadelphia,

State of Pennsylvania, have made a certain new .and useful Invention in Hub Structures-for Wheels, of which the following is a specification This inventlon relates-to hub structures for wheels.

The object of the invention is to provide a permits the wheel to be readily detachable from its supporting hub and replaceable thereon, and when replaced upon its hub to be clamped and secured thereon.

A. further object of the invention is to provide means for locking the detachable wheel upon its carrying -hub, the locking means being released by the application of a spanner or other suitable tool to release the clamping nut. 4

Further objects of the invention will appear more fully hereinafter. 0

The invention-consists substantially in the construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown by the accompanying drawing and finally pointed out in the appended claims.

Referring to the .drawlng Figure 1 is a sectional view in side elevation of a hub structure embodying my, invention.

Fig. 2 is a partial sectional and end elevation view taken on the line 2, 2, Fig. 1, and looking in the direction of the arrows.

The same part is designated by the same reference numeral wherever it appears throughout the several views.

Tn structures of vehicle wheels such as are employed extensively in connection with motor vehicles, and particularly with wheels of the wire spoke type it is desirable to provide means by which the wheel-may be readily detachable and'removable from its hub and quickly and easily applied thereto, and

. securelyclamped in place in such manner as to be locked in position when applied. It isalso desirable to provide means to prevent so the accidental disengagement or release of ends in any the locking means employed by reason of the backing off of the clamping nut usually employed in connection with looking devices, through jolts, shocks, or otherwise. It

is also desirable to provide a hub structure for detachable or deniountable wheels which is simple, economical to manufacture, and efiicient in operation. It is among the special purposes of my present invention to provide a hub structure for detachable demountable wheels which secures the advantages and desirable characteristics referred to by means of the characteristic features of construction, as will be more fully hereinafter set forth.

Referring to the drawing :--1 designates theouter shell which forms a part of the wheel proper. The axle 2 is secured to an inner hub shell 3 and is held in place relative thereto by means of the nut 4. The outer shell 1 is outwardly flared as indicated at 5 to form a pocket 6 circumferentially therein, which accommodates a stop plate 7 which carries the stop lugs 8. The outer end of the hub shell 3 is provided with exterior screw threads '00 allow the hub cap 9 to screw thereover. The hub cap 9 I prefer to make in two shells, preferably of pressed steel of relatively different diameter, and telescoped the oneover the other, and suitably secured together at their inner and outer desired manner. In the outer shell of the pressed steel hub cap is located a transversely extending slot 10 to receive the safety latch 11. The slot 10 as shown is parallel to the face of the hub cap. The

safety latch is pivoted on a pin 12 extend- -1ly'disengaging the locking portion of the latch from the teeth 8 when the latch is rocked about the pin 12 as its center. A curved spring 15 anchored in the hub cap and secured to the latch 11 as shown nor mally holds the latch in its locking position relative to the stop plate teeth 8. The outer shell of the pressed steel hub cap is provided with two holes 17 and 18 for-wrench pins forming part of a wrench or. spanner of any desired. construction. Opposite one of the holes, namely, 17, is located the tail of the safety latch'11. ,As the pointed pins of the Wrench enter the holes 17 and 18 of the hub cap the pin entering the hole 17 engages the .tail' of the latch'moving it outwardly from the center of the hub cap. This depresses the locking portion 13 of the latch against action on the hub cap it is turned up on the threads of the hub shell and after being brought to of the spring 15 about the pivot pin 12 as a center thereby bringing it flush with the outer surface of the hub cap. The hub cap may then be. readily removed; by turning it on ts threadson the hub shell 3. lmputting a seat the wrench is withdrawn. -The spring forces the locking portion 13 ofthe latchill outwardly from the surface of the hub cap.

, springfautomatically moves the latch into looking position and holds it there. The locking "ortion. 13 of the latch 11 presses againsttlle top plate teeth 8 and thereiis noopportunity for it to disengage asthe front of the latch lockingsurfaoe' is made. circum- 1 'ferentialjrelative tothe pivot point 12 thereof. Any tendency for the hub cap to back oficauses the latch to press harder against the'sitop plate teeth as will be readily understoo.

Having now set forth the objects and natureoi my invention, and having shown and described a structure"'embodying the characteristic'features thereof, what'I claim as new anduseful and of my own invention and desire to secureby Letters Patent, is:
